RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Scott Spurrier 2020-05-20 16:59:32 UTC 
Description of problem:

NullPointerException after updating to tzdata-2020a-1.el7.noarch and tzdata-java-2020a-1.el7.noarch

Version-Release number of selected component (if applicable):

java -version && rpm -qa | grep tzdata
openjdk version "1.8.0_252"
OpenJDK Runtime Environment (build 1.8.0_252-b09)
OpenJDK 64-Bit Server VM (build 25.252-b09, mixed mode)
tzdata-java-2020a-1.el7.noarch
tzdata-2020a-1.el7.noarch

How reproducible:

Always

Steps to Reproduce:

In jshell:

1. import java.time.*;
2. import java.time.format.*;
3. ZonedDateTime.parse("20170505T173000.000Z", DateTimeFormatter.ofPattern("yyyyMMdd'T'HHmmss'.'SSSz"))

Actual results:

|  Exception java.time.format.DateTimeParseException: Text '20170505T173000.000Z' could not be parsed: null
|        at DateTimeFormatter.createError (DateTimeFormatter.java:2017)
|        at DateTimeFormatter.parse (DateTimeFormatter.java:1952)
|        at ZonedDateTime.parse (ZonedDateTime.java:598)
|        at (#3:1)
|  Caused by: java.lang.NullPointerException
|        at DateTimeFormatterBuilder$PrefixTree.prefixLength (DateTimeFormatterBuilder.java:4527)
|        at DateTimeFormatterBuilder$PrefixTree.add0 (DateTimeFormatterBuilder.java:4396)
|        at DateTimeFormatterBuilder$PrefixTree.add (DateTimeFormatterBuilder.java:4391)
|        at DateTimeFormatterBuilder$ZoneTextPrinterParser.getTree (DateTimeFormatterBuilder.java:4138)
|        at DateTimeFormatterBuilder$ZoneIdPrinterParser.parse (DateTimeFormatterBuilder.java:4249)
|        at DateTimeFormatterBuilder$CompositePrinterParser.parse (DateTimeFormatterBuilder.java:2370)
|        at DateTimeFormatter.parseUnresolved0 (DateTimeFormatter.java:2107)
|        at DateTimeFormatter.parseResolved0 (DateTimeFormatter.java:203

Expected results:

$3 ==> 2017-05-05T17:30Z

Additional info:

Downgrading the tzdata and tzdata-java packages works around the issue.  

# yum downgrade tzdata
# yum downgrade tzdata-java

# java -version && rpm -qa | grep tzdata
openjdk version "1.8.0_252"
OpenJDK Runtime Environment (build 1.8.0_252-b09)

tzdata-2019c-1.el7.noarch

Comment 2 Andrew John Hughes 2020-05-26 17:12:32 UTC 
I'm not able to replicate this locally on RHEL 8:

$ rpm -qi tzdata
Name        : tzdata
Version     : 2020a
Release     : 1.el8

$ cat RH1838229.java 
import java.time.*;
import java.time.format.*;

public class RH1838229 {
    public static void main(String[] args) {
	System.out.println(ZonedDateTime.parse("20170505T173000.000Z", DateTimeFormatter.ofPattern("yyyyMMdd'T'HHmmss'.'SSSz")));
    }
}

Will try on a RHEL 7 box.
Comment 4 Andrew John Hughes 2020-06-05 01:15:19 UTC 
Similar issue in bug 1837376 for Fedora.
Comment 14 list_custom_itonlineapps_rhn 2020-07-16 13:25:01 UTC 
This problems happens with all distributed jvm. The workaround, downgrading tzdata-java, is not a real solution. Is there any release date for it ? It's critical for us, it break production code.
Comment 16 Andrew John Hughes 2020-08-17 21:47:14 UTC 
This should have been fixed in the batch of security updates for July.

Which version of RHEL & java-1.8.0-openjdk is the customer using?
Comment 17 list_custom_itonlineapps_rhn 2020-08-18 08:24:36 UTC 
It's now OK for me.
Comment 19 errata-xmlrpc 2020-09-29 19:54:11 UTC
